- [HDF5 (Q61080677)](https://www.wikidata.org/wiki/Q61080677)
- [HDF4 (Q63065200)](https://www.wikidata.org/wiki/Q63065200)
- [Highly Scalable Data Service (Q114859023)](https://www.wikidata.org/wiki/Q114859023)
- [HDFView (Q130060108)](https://www.wikidata.org/wiki/Q130060108)

## Example
List subjects that are capable of reading or writing [HDF](https://www.wikidata.org/wiki/Q1069215):
```sparql
SELECT DISTINCT ?x ?xLabel ?url WHERE {
{ ?x wdt:P1072 wd:Q1069215 . } # Something that can read HDF
UNION
{ ?x wdt:P1073 wd:Q1069215 . } # Something that can write HDF
OPTIONAL { ?x wdt:P856 ?url. } # Official website
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
}
```
